I smile and wave at police cars

... And if they could hear me I would shout, "Keep up the good work!"

I have this utopian idea that if we treat police officers like they have an honourable job instead of calling them piggies and flipping the bird, then they may too see themselves as an important honourable people and corrupt cops may be no longer... The eventual goal of course Always being World Peace! :D

(Kinda doesn't work as well when you are waving and smiling while breaking the speed limit zooming past them :/ )
